In all of the calculations, the ordinate intercept c has been ignored. can you use c consistency check? if so, how? 1. as the velocity of the glider increases, does the accuracy of the motion sensor increase or decrease? 2. in the configuration of investigation 1, for the upwards part of the motion, how does friction affect the total energy of the glider? how does it affect the total energy for the downwards part of the motion? 3. for the configuration of investigation 1, draw force diagrams for all the forces on the glider including friction, for both the case of upwards and downwards motion. 4. for the configuration of investigation 2, what is the acceleration of the glider if m' rightarrow infinity? 5. for the configuration of investigation 2, what is the change in potential energy from the moment of release to the moment of collision with the bumper? considering the kinetic energy of the system just before it crashes into the bumper what is the change in total energy of the system? is the change in energy positive or negative. explain whether your result makes sense.
